उत्तर
Organs of the female reproductive system in humans are:
- A pair of ovaries: They produce eggs (ova).
- Oviducts or fallopian tubes: Through these eggs travel, sperms and ovum meet here and fertilisation takes place.
- Uterus (womb): Development of fertilised egg and baby occurs here. The lower part of the uterus is called the cervix.
- Vagina: The cervix is connected to the muscular tube-like vagina. The sperms enter the uterus through the vagina.
- Ovary: It is the primary female sex organ. Its main function is the production of egg or ovum and the female reproductive hormones. It is a solid, oval or almond-shaped organ. It is 3.0 cm in length, 1.5 cm in breadth and 1.0 cm thick. It is located in the upper lateral part of the pelvis near the kidneys
